Question

我收到此错误

“没有为端点'importExchangesOutboundAdapter'定义轮询器”。下面是我对Spring批量远程分块的配置。

我正在使用spring integration amqp。

<rabbit:connection-factory id="connectionFactory"
    port="${rabbitmq.port}" host="${rabbitmq.host}" username="${rabbitmq.username}"
    password="${rabbitmq.password}" />

<rabbit:template id="amqpTemplate"
    connection-factory="connectionFactory">
</rabbit:template>

<rabbit:queue name="${import.exchanges.queue}" />
<rabbit:queue name="${import.exchanges.reply.queue}" />

<int:channel id="importExchangesChannel">
    <int:queue />
</int:channel>


<int:channel id="importExchangesReplyChannel">
    <int:queue />
</int:channel>


<beans:bean id="importExchangesMessagingTemplate"
    class="org.springframework.integration.core.MessagingTemplate"
    p:defaultChannel-ref="importExchangesChannel" p:receiveTimeout="${import.exchanges.reply.timeout}">
</beans:bean>

<amqp:outbound-channel-adapter id="importExchangesOutboundAdapter"
    channel="importExchangesChannel" />

    connection-factory="connectionFactory" channel="importExchangesReplyChannel"
    queue-names="${import.exchanges.reply.queue}" />

Answer 1

您定义的端点importExchangesOutboundAdapter具有通道importExchangesChannel来轮询消息，因为该通道是Queue通道，需要配置轮询器以供消息使用。

简单的答案是定义如下的全局轮询：

<int:poller default="true" fixed-delay="100"/>

没有为端点出站适配器定义轮询器
